Coursework b is a project based assessment completed as part of the junior cert science course the concept is quite simpleyou can earn up to 25% of your junior science mark before you sit the exam by completing 2 investigations the states exam commission (the folks who write the exam) give you three titles one. I am conducting this experiment to further my understanding of osmosis the increase or decrease of the size of the potato cylinder can be explained by osmosis introduction:- the core scientific principle, related to my investigation is that of osmosis, below i intend to relay information thus osmosis:- osmosis is basically a.
Full-text paper (pdf): inquiry in the biology classroom - an osmosis experiment. Osmosis is a type of diffusion involving water molecules and a semi-permeable membrane they move from areas of high water concentration, such as dilute solutions of say, sugar, to areas of low water concentration, such as concentrated solutions of sugar, until there is an equal concentration of water molecules on.

I recently did the osmosis potato experiment, where you cut strips of potato and leave them in different concentrations of sucrose solution overnight then you work out the change in mass, and the percentage change in mass i need three limitations, and ways to overcome them, the one i already have is the.
Biology coursework: how the concentration of sucrose affects osmosis in plant cells aim: to investigate how changing the concentration of sucrose can affect the osmosis in plant cells research definition of osmosis: osmosis is the movement of water molecules from an area of high water concentration (weak.
The purpose of this investigation is to examine the effect of varying the concentration of a sugar solution (sucrose) on the amount of osmotic activity between a potato piece and the solution introduction osmosis is a special type of diffusion which involves the movement of water molecules through a. Biology coursework: effect of sugar solution on potato chipsplanningbefore planning the experiment, i will research osmosis, so that i can make predictions this will help me to discover how to make this investigation fair and safe planning ahead will. Science coursework: investigating osmosis in potato tissue what is osmosis osmosis is the passage water takes from as dilute concentration to a more concentrated solution via a semi/selectively permeable membrane water molecules will diffuse from the dilute solution into the more concentrated solution through the. Gcse biology coursework osmosis: - the potato experiment background information osmosis can be defined as the movement of water across a semi- permeable membrane from a region of high water concentration to a region of low water concentration the semi-permeable membrane allows small particles through it.
